Question

com cálculo por favor​

Answer 1

Resposta:

Explicação passo-a-passo:

a)  $\frac{10^{2} *10^{4}}{10^{3}} =\frac{10^{2+4}}{10^{3}} =\frac{10^{6}}{10^{3}} =10^{6-3}=10^3$

b)  $\frac{7^{-6} *7^{2}}{7^{5}} =\frac{7^{-6+2}}{7^{5}} =\frac{7^{-4}}{7^{5}} ={7^{-4-5}=7^{-9}$

c)  $=\frac{2^{2}*2^{-4}}{2^{3}*2} =\frac{2^{2+(-4)}}{2^{3+1}} =\frac{2^{-2}}{2^{4}} =2^{-2-4}=2^{-6}$

d)  $=\frac{3^{-2}*3^{-4}*3^5}{3^{-10}} =\frac{3^{-2+(-4)+5}}{3^{-10}} =\frac{3^{-1}}{3^{-10}} =3^{-1-(-10)}=3^{-1+10}=3^9$
